Sometimes it can help to clear your entire dnld & incomplete list, if that's what you were asking. This was certainly true in the earlier versions. Giving it a clean slate so to speak (& also deleting the prefs in the incomplete folder & prefs folder (labelled .limewire) Has anything else changed since you notices this change? (OS update/new apps, etc.)

There's 2 thing s I might suggest, again suggesting some reference reading for a few threads that may hold the solution:
